Question

Which expression is equivalent to (2) -3 (4) ô?

Answer 1

if any number power of 0 is 1

so, (4)^0 =1

if any number power of -1 is equal to one divide this number.

like;

a^(-1) = 1/a

Therefore,

2^(-3) = 2^(-1) x 2^(-1) x 2^(-1)

= 1/2 x 1/2 x 1/2

Hence solution of 2^(-3). (4) ^0 is,

1/2 x 1/2 x 1/2 x 1
